1. Determine the total number of birds that you counted so far
- Refer to the exercise introduction for an example of how to use a for loop to iterate over an array.
- Use a helper variable to store the total count and increase that variable as you go through the array.
- Think about the correct initial value for that helper variable.
- Refer back to the array concept to recap how to retrieve values from an array.
2. Calculate the number of visiting birds in a specific week
- This task is similar to the first one. You can copy your code as a starting point.
- Think about which indexes in the array you would need to take into account for week number 1 and 2, respectively.
- Now, find a general way to calculate the first and the last index that should be considered.
- With that, you can set up the for loop to only iterate over the relevant section of the array.
3. Fix a counting mistake
- Again, you need to set up a for loop to iterate over the whole bird count array.
- This time you only need to visit every second entry in the array.
- Change the step so the counter variable is increased accordingly after each iteration.
- In the body of the for loop you can use the increment operator to change the value of an element in an array in place.
